      @shauncro Nope, if I look at my user manual, I need a bit more. Fiddling and will post a bit later what I happen upon. But still getting everything up and running.

      Lets just get one thing straight....

      You don't own a Delta! It's true, you don't!

      It owns you!

        @shauncro Leadshine contacted me and recommended the Differential Connection option wired as follows:

        03335e0b-d1fa-4a88-86a7-0830baa00198-image.png

        I tried this but it tripped the "Motor speed out of control" alarm right away even before sending a G1 command to turn the servo.

        @jay_s_uk I added T5:5:10:10 to the config but I am still receiving the alarm.

          @code7 can you share the full datasheet for the driver. Thanks

              Wow, this is a pretty sophisticated servo controller. I'd like to know more about it in case I want to use one like it in the future. Can you share some more information about your setup?

              • What motor do you have connected?
              • What encoder do you have connected?
              • Are you configuring it using the RS232 or RS485 serial connection?
              • Did Leadshine supply you configuration software for a Windows machine?

              There seem to be a lot of things to get right before it's going to move at all, and then tuning the servo controller can get complex, but I think if you go step-by-step you'll get it running.

              I've designed servo controllers in the (long ago) past and have used many different types, so I'll try to help as much as I can.

                Page 67 of your manual says this may be caused by:

                • UVW connection error
                • Encoder error

                Do you know that you have the motor U, V and W wires connected to the correct place on the driver?

                Do you know that the encoder is correctly connected to the driver?

                Sometimes, the motor has a connector that's perfect and things can't get out-of-order, but I don't know what you've got, so I' apologize if this is a dumb thing for me to ask you.

                  @alankilian Thanks for looking into this. The motor is a Leadshine

                  Here is the response from Leadshine: "Motor speed out of control " this Alarm is from 1XD controller.
                  Please check controller electronic/PPR setting ,make it correspond to servo driver and machine transmission devices.

                  I downloaded the Leadshine software to configure it but am waiting for an RS232 cable to test it out.

                  I'm using the ELD2 Servo controller.

                    Here's what I would do: (Step 1 of many)

                    Disconnect the 1XD and connect the motor to the servo controller.

                    Do not connect anything else to the servo.
                    Apply power to the servo drive.
                    What do you get for blinking lights or codes on the servo controller?

                    Send us a photo of the setup.

                      Hey Code,

                      I have MOVEMENT! But only on the older drivers which are the ACS806

                      Here's my config

                      I changed my 1XD to address 20 so configure for your address

                      This is still testing, so treat as test code. I'm still discovering, I do have to edit the Gear Numerator and Gear Denominator on the driver it self, which means you need your cable, I also had to set a few things in the driver for it to work, not sure what yours will be but here is a pic of what I set to get a few bits of rotation. I need to figure out what the gear denominator and numerator role play in this, also, I need to play with the timing in the config, but hey, it moves with no errors. So I'm chuffed for now.

                      Wiring for this driver is very different than the eld5 I have, but, I needed the alarm+ and Alarm- connected to IO0.0 out with inverted and pulled up,

                      55cf5064-d274-4b45-953c-c3843f45bce9-image.png

                      Then all the dir+/- Pul+/- and Ena+/- to their corresponding pins, and my settings in the software for the driver are this

                      4320c851-fa28-4769-aea7-9fdff0277f03-image.png

                      I must say that the driver software for the ACS series of drivers is pure K@K. Nothing under the motor parameters saves. And It seems no one in leadshine believes in firmware updates 😐

                      Will post as I figure out stuff hopefully to help.

                      Lets just get one thing straight....

                        @shauncro I see my enable motor in the pic is active high, this should be set to low.

                        But what I find weird, is I only get movement for a 1/4 of the motor, so 50mm to -250mm if I disable motors and turn it to the next pole, I can move with in that pole, but the numbers are different. 50-350 etc currently have my Gear numerator set 1:1 with the denominator. Motor movement is slow though.

                          @alankilian Thanks for double checking. Everything is connected properly.

                          With everything connected or disconnected I am still receiving the blinking green light with no errors. I'm going to try a simpler motor/driver for now and I may come back to the Leadshine system later.

                          @shauncro Thanks for the details. I tested your config.g and servo driver settings with my Leadshine setup and am not getting any movement. If I come back to this setup and have success I'll let you know.

                            If you want to send one motor driver and one motor to me I'll hook it up and getting working for you and send it back. No charge for postage or anything.

                            I only have a Duet2, but getting it working on that system will certainly get it working on your system also.

                            I've done this for other people in the past and have had success.

                            I'm in Cambridge, MA so you can estimate postage.

                            Let me know if you want to try this to get you a jumpstart on getting this working.

                                @code7 OK, I've got your system setup on my bench.

                                I can connect using the Leadshine software on a Windows-10 computer using a USB-to-RS232 and your cable and I can read values from the stepper driver and I can command motion and the motor turns.

                                I also hooked up a pulse-generator and I can enable the stepper driver and the motor turns when I generate step signals.

                                So...... I don't have a Duet-3 so I can't hook up the 1XD board you sent, but I'll hook up my Duet2 and see if I can get the motor to move using GCODE from the Duet2.

                                  @code7 I now have the Duet controlling the stepper motor through axis U driver 5 step/direction outputs.

                                  I'll go back through this thread and see what I have hooked up differently than you did.

                                  I really just hooked:

                                  • Hooked PUL+ to Duet2 Step
                                  • Hooked PUL- to Duet2 Ground
                                  • Hooked DIR+ to Duet2 Direction
                                  • Hooked DIR-- to Duet2 Ground
                                  • Hooked ENA to Leadshine ground
                                  • Hooked the COM+ to leadshine 24 Volts DC

                                  I'll read some more and get back to you.

                                    With everything connected or disconnected I am still receiving the blinking green light with no errors.
                                    ...
                                    Leadshine contacted me and recommended the Differential Connection option wired as follows:

                                    03335e0b-d1fa-4a88-86a7-0830baa00198-image.png

                                    The blinking green light means the Leadshine motor driver is not enabled.
                                    The green light needs to be solid on when the driver is enabled.

                                    You absolutely must NOT connect EN+ to COM-IN since COM-IN is between 24 and 70 Volts! You might have dodged a smoke-event because you may not have had a common ground between the 1XD and the Leadshine power supply.

                                    I'll look in to how to hook up the enable properly and write again.

                                      I know you may have different hardware, but I have 2 Clearpath SDSK servo/steppers running from Duet step and direction outputs and they are providing awesome acceleration, no vibration and near zero noise at any speed.

                                      They are a bit expensive and the specs are quite overkill, but they are highly recommended.

                                        @alankilian Thanks for the update. Is there any other straightforward way to test the LeadShine encoder on the Duet2 or would you need a Duet3?

                                            @code7 Everything works perfectly using my Duet2.

                                            I think you just had the enable signal hooked up incorrectly.

                                            • Hook COM+ from the Leadshine to +5 Volts on the 1XD
                                            • Hook DI3/ENA from the Leadshine to the enable output on the 1XD

                                            After that, you should be ready to roll.

                                            I'll ship everything back to you soon.
